The reason why the Ming army was reluctant to use this kind of flowering bomb was also very simple.

Because the explosion of this flowering bomb is too frequent.

The flowering bomb of this era was actually made by igniting it with a fire rope.

That is, there was an arcore on the shell, which was filled with a large amount of gunpowder.

And because it is a rear-loading artillery, the barrel of the gun also contains some propellants.

When the barrel of the cannon is filled with flowering shells, the arquebus of the flowering cannon needs to be lit first, and then the arquebus of the cannon propellant needs to be lit.

At this time, the propellant was lit first, and the flowering bomb was shot, and when the flowering bomb landed, it would explode among the enemy's men and horses.

When you think about it this way, it doesn't seem like there's much of a problem.

But in practice, the Ming army immediately discovered the unreliability of this method.

That is, when the propellant in the barrel explodes, the spark will invade the inside of the shell, directly causing the shell to bloom in the chamber.

That is, this flowering shell exploded before it came out of the barrel.

Therefore, the possibility of artillery blowing up is very high.

Therefore, this approach is not actually advisable.

Only then did the Ming army directly abandon this flowering shell and use backward solid shells instead.

Now Zhu Youxiao wants to solve this kind of problem.

His so-called method was to use thundermercury instead of the fire rope for ignition.

Thundermercury is a very unstable thing.

When he encounters a violent impact, this thunder mercury will explode instantaneously.

If Zhu Youxiao had made the thunder mercury, it could have been loaded directly on top of the shell.

By the time the shell hits the ground, the thunder mercury can ignite the gunpowder inside the flowering shell.

This directly solves the possibility of the shell exploding in the chamber.

In fact, in the eighth century AD, the Arab alchemist Jabir ibn Hayyan discovered and prepared nitric acid when he was drying saltpeter.

This is the earliest human record of nitric acid.

Zhu Youxiao stood in the distance and sent someone to send an order to go over and directly dry distill the saltpeter they transported.

The reason why Zhu Youxiao couldn't do it himself in the past was that the danger of making mine mercury was too high.

If he is gone, Da Ming will really not be saved.

If he is alive, then this Da Ming can be saved again.

Therefore, in this case, even if he has a clear conscience, it is impossible for him to go over and make nitric acid in person.

But because Zhu Youxiao did not personally go to the front to command, it was too difficult for this kind of thunder mercury to be made.

Zhu Youxiao's forehead was also sweating.

But fortunately, under his command, nitric acid was finally made.

Zhu Youxiao looked at Sun Yuanhua next to him.

"It's called nitric acid, and it's very dangerous, and you can gradually train craftsmen to do this work in the future, and you can even give them a settling-in fee."

"The craftsmen who participated in the production of thundermercury here today can go directly to the account office and get a settlement fee of 100 taels later."

"In the future, when they make this nitric acid, you must not come close, it will be extremely damaging to people's bodies."

Sun Yuanhua was very moved in his heart, he didn't expect Zhu Youxiao to care so much about his body.

Even for the craftsmen below, they did not abandon it like thin shoes.

A hundred taels of silver is a lot.

Some ordinary people in the Ming Dynasty can't spend ten taels of silver a year.

If it is really a bitter family, if they can only eat two nests per meal, this silver is enough for them to spend twenty or thirty years.

Sun Yuanhua bowed on the spot.

"On behalf of these craftsmen, thank Your Majesty for your kindness."

"How can Weichen be so virtuous, can be so valued by His Majesty, the minister will definitely do his best, and then die."

Zhu Youxiao sighed.

He felt a little emotion in his heart, people in this era are still too simple.

Or the prince of heaven and earth, the king wants the minister to die, and the minister has to die.

In fact, Zhu Youxiao's essence is not that he cares much about Sun Yuanhua.

It's just that he doesn't want to lose such a talent.

Zhu Youxiao knew that now that nitric acid had been manufactured, the next step would be even more dangerous.

He instructed the craftsmen in the shed, and according to his method, mercury was mixed with nitric acid.

The manufacture of mercury has a long history in China.

Legend has it that in the imperial mausoleum of Qin Shi Huang, there are rivers made of mercury.

Therefore, the manufacture of mercury does not have to worry about Zhu Youxiao himself.

It's just that in this process, Zhu Youxiao is very worried.

Subsequently, after the mercury was completely melted in, Zhu Youxiao commanded the craftsmen to mix ethanol, that is, alcohol.

Making alcohol is nothing more than distilling and purifying the wine.

Zhu Youxiao even knows how to make thunder mercury, let alone distilled alcohol.

Thankfully, they succeeded the first time.

Thundermercury has been made!

Through the method commanded by Zhu Youxiao, the craftsman took the final made thunder mercury to 20 steps away from Zhu Youxiao's face.

Zhu Youxiao hesitated for a moment, but finally decided to walk over and observe the state of the thunder mercury.

"Give it a try!"

Then they went to the test site and threw the thunder mercury directly to the ground.

"Bang", thunder mercury exploded.

Such a small bit of thunder mercury exploded with such great power.

Sun Yuanhua only felt his ears buzzing.

His eyes widened and he looked at Zhu Youxiao in disbelief.

"Your Majesty, this thunder mercury has so much power, it's really a miracle, a miracle!"

Zhu Youxiao didn't laugh at Sun Yuanhua.

Because he knew that if it was the first time he saw such a thing as thundermercury, he would be very surprised.

I saw Sun Yuanhua say excitedly: "This thunder mercury is too powerful!" ”

"If our flowering bombs are filled with this kind of thing, the power of the flowering bombs is simply unimaginable."

Zhu Youxiao squinted his eyes and glanced at Sun Yuanhua.

"If this flowering bomb is filled with thunder mercury, then you will only have one fate."

"That is, these flowering bombs can blow you up into the sky on the way."

That's right, although thundermercury is powerful, it's too unstable.

Even in later generations, when the US military adopted a new type of fuze, it still had to store and transport the fuse of the shell separately from the body of the shell.

Only when the shell is about to be put into service will the US military twist the fuse to the shell.

And in this case, only about 30 percent of the fuses have been improved.

One can imagine how unstable such a thing as thundermercury is.

Zhu Youxiao looked at Sun Yuanhua, and he was already a little worried.

What he was most afraid of was that Sun Yuanhua didn't know whether he was alive or dead, and ignored his request.
